I thought I'd straighten out this confusion a little bit...

Quote:

They are the ones, but they are a 1970 only item. I suspect the previous owner has attached a 70 rear valence to your car. Here is a pic. of a 70(top) and a 71(bottom) rear valence. The 71 valence does not have the four holes for the brackets like a 70 does. It should be noted that 71 cars DID have the four stud holes on the brace under the rear pan, but they were not used to intall the rear valence. That center bracket on the 71 valence was used for that.

Are you talking about the four threaded holes in the rear filler panel? Are those holes only used on the 70 model? I believe my 73 has the braket like the "lower" one in your picture but the rear filler panel still has the four threaded holes in it.




Most of the confusion is caused by using different terms to describe the same part of the car. M46rat called it the "brace under the rear pan" while burdar called it the "rear filler panel". It's also known as the rear crossmember.

M46rat talked about BOTH the four holes in the 1970 only rear valence, AND the four threaded holes in the rear crossmember. The four threaded holes in the rear crossmember are present on all challengers, but were only used in 1970. That is basically what M46rat and burdar both said.


Quote:

The holes are not threaded, they are just four punched holes.




M46rat was talking about the four holes in the 1970 only rear valence. They are not threaded. The rear valence is also known as the rear stone shield, or rear filler panel, hence the confusion.

I hope that helps to clear it up for anyone who reads this in the future.
